描述 | Dienogest is a specific progesterone receptor agonist with potent oral endometrial activity and is used in the treatment of endometriosis. It is available for use as an oral contraceptive in combination with ethinylestradiol. It has antiandrogenic activity and as a result can improve androgenic symptoms. It is a non-ethinylated progestin which is structurally related to testosterone[3]. Dienogest inhibits ovulation, produces secretory transformation of the endometrium and has antiproliferative effects. Oral dienogest 2 mg/day plus ethinylestradiol 30 micrograms/day provides effective contraception (Pearl Index approximately 0.2). Cycle stability is good during long term use of this combination; irregular vaginal bleeding was evident in 6% of women after 12 months' use. Androgenic symptoms (including hirsutism, seborrhoea, alopecia, acne vulgaris and hair and skin greasiness) improved in women treated with dienogest plus ethinylestradiol[4]. Dienogest 2 mg/day was superior to placebo in reducing pelvic pain, with similar results to buserelin, leuprorelin, leuprolide acetate and triptorelin, in controlling symptoms associated with endometriosis. Dienogest 2 mg/day was effective in reducing endometriotic lesions. The extended therapy with dienogest 2 mg/day also showed an improvement in pelvic pain after 24-52 weeks with tolerable side effects[5]. Dienogest 2 mg once daily is effective and safe in the long-term management of EAPP in Chinese women with endometriosis, with progressive decreases in EAPP (endometriosis-associated pelvic pain) and bleeding irregularities during continued treatment[6]. |
